Turns an image into an NxM array of emoji for making jumbo-emoji in slack.
It turns out that emoji in slack can be displayed with no whitespace between them. This means you can use NxM emoji tiles to display an image of any kind as an "emoji".
Note you must have
npm installed. If you don't, go to nodejs.org and follow the install instructions there.
$ npm install -g slack-emoji-tiles
Usage is pretty simple:
$ slack-emoji-tiles path/to/img -o path/to/output
image: (required, default) the path to the image you want to slice
outputDir: (optional) the path to output the sliced images to. If no value is passed, a folder with the title of the image is created in your working directory as the output path
maxTiles: (optional, default 10) the maximum number of tiles in either dimension to generate
tileSize: (optional, default 128) the size in pixels the resulting tiles should have. Slack's maximum emoji-size is 128x128
showUsage: (optional, flag) if present, an example usage of the tiled emoji is printed
Pass short aliases with a single
- and the full names with
For the following example, test.jpg is an image with the intial dimensions 1557 x 2177
$ slack-emoji-tiles test.jpg -o emoji -t 2 -uAfter you've uploaded the output sliced emoji to slack, use your jumbo emoji like::test-0_0::test-0_1::test-1_0::test-1_1:$ lsemoji/ test.jpg$ ls emoji/test-0_0.png test-0_1.png test-1_0.png test-1_1.png
